We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.
Dmitri MendeleevRead
It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this refers in equal measure to the relations of man - social and political - and to the entire universe as a whole.

All quotes →No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.

The most all penetrating spirit before which will open the possibility of tilting not tables, but planets, is the spirit of free human inquiry. Believe only in that.

The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.
Dmitri MendeleevRead
The edifice of science not only requires material, but also a plan. Without the material, the plan alone is but a castle in the air-a mere possibility; whilst the material without a plan is but useless matter.
